The police officer in charge of West Bengal Chief Minister Mamata Banerjee's security when she was injured during a visit to the state's Nandigram, just weeks before the elections, has been suspended by the Election Commission. "Vivek Sahay IPS, Director Security shall be removed from the post of the Director Security and be placed under suspension immediately. The charges must be framed against him within a week for grossly failing in discharge of his primary duty as Director Security to protect the Z+ protectee," the Election Commission said, soon after declaring that the incident was an accident and not an attack.
